How do I generate a radar chart with an API?
Send a POST request to the ChartQuery chart endpoint with your data as JSON. The API returns a rendered image directly. You can also use GET requests with URL parameters for simple cases. No API key is required for basic usage, anonymous access is available with 60 requests per hour.

Is the Radar Chart API free to use?

How does AI radar chart generation work?
Describe what you want in plain English, mention the chart type, data topic, colors, and style. ChartQuery's AI interprets your prompt and generates a fully configured radar chart image. You can also pass raw data and let the AI handle the visual layout. An API key is required for AI generation.
Can I share and embed charts generated by the API?
Yes. Add "share": true to any request to get permanent URLs. The render_url is a direct image URL you can embed in emails, documents, or <img> tags. The view_url is an interactive HTML page you can embed as an iframe. No authentication needed for viewers.
